Which is the best solution?

Hi,
I am not an experienced S7 developer. I would like to know which is the best solutions when you are writing a program.

In my program, during the first running, I save same setups values in a Data Block.
Now, my question is:
during the next cycles, I need to use this values, so, what is better? assigning this data blocks values to flags and then on the nest cycles just ask values on the flags, or directly access to the data block?

I'll very glad If someone can answer me.
Thanks.

Accessing flags is quicker and takes less memory than accessing a fully qualified DB value. Throw your scan time/memory usage into the pot, stir for an hour and hey presto.

Thank you!
